Symantec sells computer antivirus and Internet security products to consumers. Consider the Norton Internet Security product, with a list price of $69.99 sold through the retail channel. Assume that packaging and delivering Norton Internet Security to the retail channel costs $7 per unit. Furthermore, assume that annual renewals of Norton Internet Security are sold directly by Symantec through its online store as a digital download at no cost to Symantec. Outside of retail channel costs, assume that Symantec spends on average $6 per customer on sales and marketing for acquiring new customers and $1.20 per customer on sales and marketing for retaining existing customers. Let the annual discount rate used by Symantec be 12 percent and assume that a customer acquired through the retail channel must be reacquired every four years as he or she gets a new computer.
